2. If there is a fault condition the yellow LED will flash and the horn will beep in
accordance to Table D.
3. If the memory has been set the Red light will flash and the horn will give a full

Quick Test with Carbon Monoxide:
The Carbon Monoxide Alarm checks for CO gas
every 4 seconds and when exposed to the CO gas,
the red light will flash (as per Table B-1 & B-2) to
confirm that it is detecting the CO gas.
The Alarm can be tested with carbon monoxide gas
by using one of the kits that comes with the gas
either in a glass phial or aerosol can. Follow the
instructions on the kit.
If a test gas kit is not readily available it is also
possible to gas test the Alarm using a joss stick
or cigarette smoke. To do this remove the Alarm
from its base and slide the power switch to the ON
position (see figure 9). Fill a suitable size plastic bag
with smoke from the joss stick or cigarette.
Insert the Alarm into the smoke filled bag and seal it closed. Within seconds, the
red light will begin to flash (as per Table B-1 & B-2) to confirm that the Alarm has
detected the CO gas in the bag.
